Our Brumleve Kwik-Lock Assembled Easy-Off Tarp Stop is designed to allow your tarp to roll completely over the edge of the trailer when open. This gives you full access to the trailer bed for loading. The clevis and cotter pins allow for easy install or removal, especially during those cold winter months. Our Brumleve Kwik-Lock Easy-Off Tarp Stops are assembled here in the USA and widely used on side-to-side roll tarp systems.
